This invention relates to spools reels, bobhins, or like winding devices and more particularly to securing means for fastening end discs or tlanges to the body members ol such devices.

The principal object ofthe invention is to provide an improvedspool or the like, the end discs ci which are secured to the body member by :means of novel fastening elements which are exceedingly light in weight, inerpensive and; simple in construction, and well adapted to rigidly unite spool members to effectively prevent relative movement therebej tween. s e

Other objects and `leatures oinovelty will be apparent from the following speciiication Twhen read in connection with the accompanying drawing in which one embodiment oil the invention isl illustrated byway ol eX`1 ample.

ln the drawing,

Figure 1 is an elevational view of a spool embodying the principles' of my invention; one end ot the spool being shown in: vertical cross-section to'illustrate `the end `liange se= curing means;

Figure 2 is an end view ont the spool; and Figure 3 is a perspective view ot one o the fasteningelements employed.

1n Figure 1 of the drawing, there is illustrated at 10 an example of the type of spool 'or winding device which embodies the prin-- ciples ot the present invention. The sl col 1@ is seen toconsist of abody' member or arrel 11 which may be tubular or solidly constructed with openings or recesses at the ends thereof. ln the forni shown in the drawing, the bcreor opening of the body member is designated by the numerall 12. End discs ,13 provided with central apertures 14 are positioned at the ends cf the body member 11 with the apertures 14 and the opening 12 uin substantial registry. f Y

' The essential part'oftheisecuring means employedA for fastening-the discs 13 to the body members 11 comprises the element 15 which is clearly shown in perspective in Figure 3 of the drawing. The element 15 is constructed of a strand or lament which may be a cord, thread, or similar iibrous material lated cylinder 18 having an outer flange 19 y `formed thereon. The completed securing elenient 15, as shown in Figure 3, is then inserted in the end of the assembled spool so that the cylindrical part 18 formed by the convolu tions ci the wire lies against the wall ot the by the outwardly bent portions of the con volutions is adapted to overlie the margin or? the aperture 14 of the end disc 13. A plug or bushing 20 which is preferably formed 'opening 12 andthe skeleton dange 19 orrned with a slight taper 21 at its inner end and l with a bore 22 to provide a bearing for an axle, is then forced into the end ot the ool. The diameter or the greater portion ot the plug or bushing 20 is substantially the same as the diameter ofthe opening 12. Thus it will be seen that the convolutions of the securing element 415 are embedded in the niaterial forming the wall of the opening 12. As the plug or bushing 20 is driven home so that its outer surface occupies substantially the same plane as the outer surface of the end disc 13, th se portions of the convolutions f which form the iiange 19 are struck or ressed with a suitable tool and are firmly em edded in said outer surface of disc 13 around the margin of the perforation 14.

Both the body member or barrel 11 of the gmi spool and the end discs 13 must kbe made of some rigid material which is, however, soft enough to permit penetration of the fastening element therein. The bushing 2O may `be formed of metal or any other like material but is preferably constructed of wood or ber' so that the fastening element 15 may be em bedded tosome extent therein as'weil as in the wall of the opening 12 and the end disc 13, thus effectively preventing relative movement not only of the end disc 13 and the body memu ber 11 but` also of the bushing 20 and said body member,

It is conceivable that the filamentous inaterial employed in the construction of the securing elements 15 may be of thread, cord, or other fibrous materia-iiv (instead of wire as in the preferred form), thronghthe use of a suitable adhesive substance which will cause the convolutions, of the element to firmly adhere to the walls'of the opening 12, tbe disc 13 and the plug 2O in the absence of: the relative stiffness or ri 'dit of the securing ele mentas formed of wire. lt will be understood that the terms wire4, filament, or simiiar terms, as used in the claims, are meant to cover all reasonabiy suitable or equivalent sub stances which may be employed in this con nection. f o

It will thus be seen 'that by means of the present invention there has been provided an effective securing device for rigidiy connect ing the end discs or anges to the body members or barrels of s ools, reels and iihe wind= ing devices, one o the most important features of which is the simplicity and economy of construction ofthese devices, which will permit them to be manufactured cheaply andy 1n the exceedingly great numbers required by the textile, electrical and numerous other industries.

It is to be understood that various other changes and modifications may be made in the securing elements herein disclosed without departing from the scope of the present invention as defined in 'the following claims.

Having thus described the invention, what is claimed as new and desired oo be secured b Letters Patent is: v

1. In a s. ool, in combination, a body member provi ed with an opening in the end thereof, an end disc having a central aperture registering with said opening, and means for securing said disc to said body member comprising a piece of wire bent toY means for securing said disc to said body member comprising a piece of wire bent to form convolutions, portions of ene or more of which are embedded in the wall of said opening and other ortions of which are embedded in the margin of the aperture in said end disc.

3. ln a spool, in combination, a body member provided with an opening in the end thereof, an end disc having a central apen 'ture registering with said opening, means for securing said discy to said body member comprising a piece of Wire bent to form convolutions, portions of one or more of which are disposed in contact with the wali of said opening and other portions of which overiie the margin of the aperture in said end disc, and means for retainin the convolutions said wire which are 's osed said opening in firr; contactfwith said inner e. In a spool, in combinatioma body mem ber provided with an o ning in the end thereof, an end disc having a central apen -ture registering with said opening, means for securing said disc to said body member coneprising a piece/of wire bent to form convo utions, portions of one or more of which disclosed in contact with 'the wall of said opening and'other portions of which. overllie the margin of the aperture in said end `and a bushing wedgmgly inserted in seid op ening for retaining the convolutions of said wire which are dis sed within seid opening in drm contact Wit said wall.

5. In a spool, in combination, a body member provided with an opening 't e end thereof, an end disc having a central aperturel registering with said opening, means for securing said disc to said body member comprising a piece of wire bent to form con volutions, portions of one or more of which are disclosed in contact with the wall of said opening and other portions of which overlie the margin of the aperture in said end and a bushing wedgingly inserted in said opening for retaining the convolutions of said wire which are disposed` within said opening in firm contact withsaid wall, said wire also being embedded to some extent in the outerewall of said bushing. o y
